What is crucial when approaching a pedestrian crosswalk?

Answer: B — Be prepared to stop

Being prepared to stop when approaching a pedestrian crosswalk is essential for ensuring the safety of pedestrians. As a driver, you are responsible for monitoring both your speed and the behavior of pedestrians in and around these areas. By being vigilant and ready to stop, you allow pedestrians the necessary space and time to cross safely. Crosswalks are designated areas meant specifically for pedestrian traffic, and drivers have a legal and ethical obligation to yield to individuals crossing the street. Failing to stop not only jeopardizes pedestrian safety but can also lead to severe legal repercussions for the driver. The other choices involve actions that do not prioritize pedestrian safety. Speeding up could endanger individuals attempting to cross, using the horn can startle pedestrians, and yielding only when pedestrians are already in the crosswalk could lead to accidents if the driver is not prepared to stop beforehand.
